SIG SAUER TANGO-SPR 1-4x24mm SFP Rifle Scope

SIG SAUER TANGO-SPR 1–4x24mm Rifle Scope

The SIG SAUER TANGO-SPR 1–4x24mm is a low-power variable optic designed for shooters who want a broad field of view at the low end and additional target detail at 4x. This listing is for manufacturer part number SOTS41000, identified by UPC 798681710751. The exact configuration uses a 30mm main tube, a second-focal-plane Hellfire illuminated FL-4 reticle, black finish, and an included SPR-style mounting solution.

A 1–4x magnification range keeps the optic straightforward and versatile. At 1x, the scope is suited to quick target acquisition and close-range field use. Turning to 4x provides additional visual detail for more deliberate shots at moderate distances. The 24mm objective helps keep the overall profile compact while the 30mm tube provides a familiar mounting standard and internal space for the adjustment system.

Hellfire Illuminated FL-4 Reticle

The Hellfire illuminated FL-4 reticle is positioned in the second focal plane. Its apparent size remains constant as magnification changes, giving the shooter a consistent visual reference throughout the 1–4x range. Illumination improves reticle visibility against dark, shaded, or visually complex backgrounds. The reticle layout is intended to balance an uncluttered sight picture with useful reference marks for practical shooting.

Because this is a variable-power optic, reticle subtensions and hold references should be confirmed at the magnification specified in SIG SAUER’s documentation. Shooters should verify point of impact with their exact rifle, ammunition, mount position, and preferred zero rather than relying on generalized ballistic assumptions.

Compact Low-Power Layout

The catalog lists the scope at approximately 10.25 inches long with about 3.7 inches of eye relief. Those dimensions help it fit compact sporting-rifle and carbine setups without overwhelming the rifle’s handling. Eye relief still needs to be established for the individual shooter before the mount is tightened, ensuring a clear sight picture and safe clearance throughout normal firing positions.

The optic is supplied with an SPR-style mount for installation on a compatible Picatinny rail. An included mount simplifies initial setup by providing a matched starting point for height and forward offset. Final placement depends on the rifle, stock position, and shooter. All mounting fasteners should be installed and torqued according to the current manufacturer instructions.

Adjustment and Focusing Features

The TANGO-SPR provides a 60 MOA cataloged elevation adjustment range. Its parallax is factory set rather than externally adjustable, reducing the number of controls that must be managed in the field. The magnification ring allows the shooter to move between the low and high ends of the power range, while the ocular focus should be set so the reticle appears crisp to the user.

The black finish gives the scope a subdued appearance that coordinates with common rifle and mounting hardware. Its controls and proportions are designed around practical sporting-rifle use, making it a sensible option for range training, property use, and general-purpose shooting where a compact variable optic is preferred over a fixed-power sight.
